Abstract
Three new compounds, namely [Mn(phen)2(L)2] · EtOH (1), [Zn(phen)2(H2O)2]2L · 6H2O (2) and [Cd(phen)2(H2O)2]2L · 6H2O (3), where HL = 4-methylbenzenesulfonic acid and phen = o-phenanthroline, have been synthesized, and their crystal structures determined by X-ray diffraction. In the complexes the metal atoms have two different coordination environments. Complex (1) consists of neutral molecules, [Mn(phen)2(L)2], in which MnII is six-coordinated by four nitrogen atoms from two o-phenanthroline molecules and two oxygen atoms from two sulfonate ions. Complexes (2) and (3) are isomorphous, each consisting of cationic species [M(phen)2(H2O)2]2+ [M = Zn (2), Cd (3)], in which MII is six-coordinated by four nitrogen atoms from two o-phenanthroline molecules and two water molecules. The electrochemical behavior and FT-IR of these compounds were also studied in detail.
